Key Features of the Westinghouse 28000 Watt Backup Generator

The Westinghouse 28000 Watt Backup Generator is a robust solution for homeowners looking for a reliable source of backup power. Offering an impressive 28,000 peak watts and 20,000 running watts, this generator is designed to power large homes or heavy-duty equipment. The following sections break down the key features of the generator.

Power Output and Fuel Capacity

The Westinghouse 28000 Watt generator runs on gasoline and provides the following power capabilities:

  • 28,000 Peak Watts (Gasoline)
  • 20,000 Running Watts (Gasoline)

This level of wattage is ideal for larger homes or properties that require substantial power to run multiple appliances simultaneously. The 17-gallon fuel tank provides up to 11 hours of run time at 50% load, which is substantial for most household uses. The built-in fuel gauge allows users to keep track of their fuel levels, minimizing the risk of running out of power unexpectedly.

Heavy Duty V-Twin Engine

Powered by a 999cc Westinghouse V-Twin OHV Engine, this generator is designed for reliability and long-term durability. The V-Twin engine features a cast iron sleeve that ensures a longer life, with enhanced wear protection and greater operational longevity. Whether you’re powering high-energy appliances or sensitive electronics, this engine can handle the load, making it a great choice for those needing a steady and powerful source of energy.

Electric Start with Remote Key Fob

One of the standout features of the Westinghouse 28000 Watt Backup Generator is its push-button electric start and remote start capability via a key fob. This makes it incredibly convenient for users to start the generator from a distance without needing to go to the unit. Whether you’re inside the house or in the yard, you can quickly get the generator running with the push of a button, saving time and effort, especially in inclement weather conditions.

Multiple Outlets for Versatile Use

The generator comes with a variety of outlets, making it versatile enough for a wide range of applications:

  • Four 120V GFCI standard outlets (5-20R)
  • Two 50A 120/240V outlets (14-50R)
  • Two 30A 120/240V outlets (L14-30R)
  • One 30A 120V outlet (L5-30R)
  • One ST switch outlet

All the outlets are equipped with rubber covers for added safety, ensuring they remain protected from dust and moisture. These outlets are perfect for powering large appliances such as air conditioners, refrigerators, sump pumps, as well as sensitive electronics like computers and televisions. The variety of outlets allows for easy, single-cord hookup to major appliances, and it is transfer switch ready, which means you can directly connect it to your home’s electrical system for seamless backup power during an outage.

Carbon Monoxide (CO) Sensor for Safety

Safety is always a concern when operating powerful generators, and Westinghouse has taken steps to address this with an integrated CO sensor. This Carbon Monoxide (CO) Shutdown feature automatically turns off the generator if dangerous levels of CO are detected, preventing carbon monoxide poisoning and ensuring the safety of those around the generator. This safety feature is particularly important for homeowners who plan to use the generator indoors or in enclosed spaces.

Idle Control and Automatic Voltage Regulation

The generator comes equipped with automatic idle control, which automatically reduces the engine speed when there is little or no load, saving fuel and reducing wear and tear on the engine. The automatic voltage regulation (AVR) ensures stable power delivery, minimizing voltage fluctuations and making it safe for all types of electrical appliances, including sensitive electronics. This feature helps protect your devices from power surges and ensures consistent performance.

Portability and Design

Despite its large capacity and powerful engine, the Westinghouse 28000 Watt Generator is designed with portability in mind. The generator comes with reinforced steel handles, quick-release pins, and heavy-duty wheels that make it easier to transport. Whether you need to move it from storage to the outside or transport it to a different part of your property, the ergonomic design ensures that it’s manageable and convenient.

Additionally, the generator is built with a rugged steel frame, providing a solid structure that enhances its durability and lifespan.

Digital Readout for Performance Monitoring

For ease of operation, the Westinghouse 28000 Watt Generator features a digital readout that displays important performance information. This includes lifetime run hours, voltage output, and frequency. The display allows you to monitor the health of the generator, track its usage, and keep an eye on performance, ensuring timely maintenance and optimal performance.

Plug-and-Play Setup

The Westinghouse 28000 Watt Generator is designed to be user-friendly, with a plug-and-play setup. The package includes everything you need to get started, such as oil, a funnel, a battery charger, a quick-start guide, and an owner’s manual. With minimal assembly required, you can have the generator up and running in no time, making it a hassle-free solution for residential backup power.
